I drove 4 hours to to Chicago on Monday, and when I got back and checked the trip, It only logged 1 small 21 mile leg onTuesday the entire trip. Wednesday, the GPS thought we were 12000 miles away in the middle of some water. Tried removing the map card and re-seating it, and also shut the car off and on once. Ended up having to use the phone (Here NAV program) to navigate to our parking garage. Fortunately, the garage had a level 2 charger, so I was able to plug the car in. After we got back to the car 5 hours later, it was fully charged and the GPS worked fine for the rest of the trip. Car is updated to 3g and I have fairly up to date firmware. MFM has yet to log anything since we got back from the trip. I am guessing I may have to pull the magic fuse and see if that gets things going again. Strangely enough, the Sirius weather maps and database of gas stations, etc. are working and I don't have the service.However, I never used them, so they may have been working all the time anyway.

Finally pulled fuse. What a pain in the rear! That by its self didn't seem to get it going. I also ended up doing a reset on the radio as well, which lost all the settings. MFM then had me re-enter the vin on the phone app. After all that, it was back online, but did not have any of my 3 day Chicago trip other than that 1 anomalous leg in the middle of the whole mess.
